Madea;

To all whom it may bandera Be it known that l; ROBERT I. Hocus, a citizen of the United States, residir g at Castella, in the county of Shasta and State of California, have invented certain new and useful Improvements in Gage-Cocks, of which the'following is a specification.

This invention relates togag'e cocks hav ing for its primary object to` provide a suit able axial alined adjustable valve element with which is associated a suitable detach` able slug which engages with the valve seat in the valve housing, f

Another object of this invention is to as. sociate with the valve suitable means by which the slug is removed when the same has become inapt for use or the like.

A. further objectof the invention is to associate with the valve suitable finger lugs in order to facilitate the' actuation of the valve: in the valve housing so as to close communication therethrough when desired.

Gther objects as vvell as the nature, characteristic features and vscope of my invention will be more readily understood from the following description taken in connec- 'tion with lthe accoinpanyin'gdrawings and pointed out in the claims forming a part, of' this specification.

Referring to the drawings z-Figure Ms a longitudinal sectional View of the devicaj` lconstructed in accordance with my .,inve'n?v tion. illilstrating the application thereof;

Fig. 2 is a side elevation of mwimoroved valve member; Fig. 3 is an end elevation of the same; Fig. 4 is a 'front elevation of the slugrenioving disk; Fig. 5 is a side elevationof the same; and "Fig 6 is a top plan view of the improved .washer usedin the present invention.

in the drawings, `vherein is illustrated the preferred embodiment of this invention. in order to illustrate the application thereof, a

portion of a boiler 7 is provided which has formed therein a screw=threaded aperture with which is engaged one end of my im proved gage cock 8, said gage cock in the present instance leing provided with. a longitudinally extending opennig 9 which extends the-entire length thereof as shown to advantage in Fig. 1. One end of the gage coclr 8 4is provided with external screw threads 10 which engage with the screwthreads of th/e boiler 7 While the opposite end thereof is provided with internal .screw threads ll, Mounted for movement in the cock 8 is an ordinary turning plug 12 which is provided with an opening i3 therethrough adapted for alinem'ent, at times, with the opening of the gage-cock, the lower end of said turning plug 12 being reduced and provided with external screwthreads 14 which are adapted for engagement'with 'a nut 15. In order to provide a fluid tight connection, a metal `washer 16 is provided which is preferably made of lead and is provided with an annular collar 17 on one face thereof which `is formed by extending a portion of the washer upwardly atright angles 'to the body, the. outer periphery of said collar 17 being snugly engaged with the inner periphery of the gage cock 8 which is provided by the inountlng of the turning plug 1i).

therein., the lower-endet' the turning plug 12 having an annular portion thereof-cut away so as to collar 17 is engaged, the body portion of the washer being engaged with the bottom of the cock 8 while the outer face thereof is'engaged with the inner face of the washer 15, \As shown to advantage in Fig. 6, the collar 1T has an enlarged portion 18 formed on the inner periphery thereof so as to prevent movement of the washer on thevturnin'g rovide a seat with which said' Specification oi' Letters Patent. Pgtjmggd 15615116, 1915, x 'A'g'r'pltcation tiled December 27, i913. Serial No. 05,102. i

said recessprovided wlthoppositely dis-v posed longitudinally extending grooves 24 as advantageously illustrated infFigs. 2 and 3.'- Mounted in the terminal of the recess 23l 'is a disk 25 which is preferably made of a hardened4 metal such-as brass and has ex tending from the periphery thereof a pair of diametrically opposite lugs Q6, said lugs being engaged with the slots 24 and extending in a plane bevond the periphery of said valve'QQ. A slug 27 is'arranged inthe recess 23 exterior of the disk 26, said slug be- `ing. preferably made of lead and adapted for engagement with a nipple 28, the latter being formed by cutting out a portion of the gage cock 8 adjacent the spherical portion ,1U so as to provide an annular groove 29 with which is engaged therecessed end ot' the valve ihe outer end of the valve 22 is preferably enlarged to provide a disk which has mounted on the `outer face thereof adjacent its periphery a 4pair of locking teeth 5 1. which are adapted for engagement in corresponding, recesses in the operating handle 32. The handle 32 is preferably made of wood and is detachably associated with 'the disk 30 through the medium oi' a boit 33, the latter being prof vided with the' threaded shank which is en-V gaged with a threaded recess 34 of the valve 22. In order to facilitate the' actuation of the valve in the screw threaded end 1l of the gage cock 8 a plurality o finger lugs 85 are formed on the periphery of the valve 22 adjacent the disk 30, said lugs 85 being preferably of an arcuate configuration -iii' order to conform to the curvature'of the iin ers offthe operator. A

A n operation, We will assume that the opening i3 of the turning 'plug 12 is in axial alineinent with the opening 9 of `the through itsloutlet 2O by the valve 22. Howgage cock 8 and that the valve l22v is threaded-so that the slug 27 thereof is -snugly in engagement with -the nipple 28. In this case it is seen that the contents of the boiler 7 may be carried as far as the nipple 28 but ,will be prevented from communication ever7 as the valve 22, is unthreaded communication will be established through the opening 9' in the gage cock 8, the opening r1'3 inthe turning block 12 and through the nippleA 27 and the. outlet tube 20 of the spherical portion 19. Slt is obviousthat by the constant engaging lof the' slug 27 with the nipple 28 thatithe same-will after a cer- ;tain'length of time become inapt for use thereby necessitating the -removat of the vsame' therefrom which-may be readily done by merely' closing the communication 4through* the gage cockr. Communication i t is closed by exerting pressure on` the turning plug 12 through Vthe medium' of a- Wrench or any suitable tool so as to cause the opening 13 of the turning plug 12 to he thrown out of alinement with the opening 9 same has been removed from its engagement with the threads 11. The slug 27 is lthen removed by actuating the disk 25 in the opening 23 by exerting pressure on the lugs 26.

It will be understood that the above de.- scri vtion and accompanying drawings coinpreI end only the general and preferred embodiment lof my invention and that va rious minor changes in detail of construe tion, proportion and arrangement of the parts may be made within the scope ot' tho appended claims and without sacrificing any of 'the advantages of my invention.

Having thus fully described my invention, what I claim. as new and desire to secure by Letters Patent iscl. A'gage cock including a valve housing having a portion thereof formed to provide a valve seat, a valve udjustably mounted in said housing and provided with a' recess thereima slug mounted in said recess, to cngage the valve seat, and a disk arranged subjacent the slug and provided with laterally extending lugs proiecting beyond the' valve, to facilitate removal of the slug when the latter has been rendered inapt for use.

2. ygage cock including a valve housing having a valve seat, a valve mounted in said housing`r one end of which is provided with a recess, a slug mounted in said recess for engagement with said valve seat, and a disk mounted in said recess beneath said slug having lugs extending therefrom, at diametrically` opposite points' and extending through the longitudinal extending slots in said val 'e for the purpose specified. l

In testimony whereof I aix my signature in presence of two Witnesses.
